UNITE STATES G. W. WAL'ION AND H. EDGARTON, OF WILMINGTON, DELAWARE.

METHOD 0F TURNING ELLIPSOIDAL FORMS.

Specification of Letters Patent No. 15,445, dated July 29', 1856.

To all whom it may concern.'

Be it known that we, G. W. VVALTON and H. EDGARTON, of Wilmington, in the county of Newcastle and State of Delaware, have invented a new and Improved Machine for Turning Handles for Pails, Tools, Sac.; and we do hereby declare that the following is a full, clear, and exact descriptionof the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a longitudinal vertical section of our improvement, Fig. 2 showing the plane of section. Fig. 2 is a plan or top view of the same. Fig. 3 is a transverse vertical section of the same, showing the plane of section.

Similar letters of reference indicate corresponding parts in the several gures.

The nature of our invention consists in the employment or use of intermittingly rotating feed rollers and expanding cutters fitted within a hollow rotating cylinder, the above parts being arranged and operating as will be hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a rectangular frame in the upper part of which a hollow shaft B is placed, said shaft working in proper bearings (a) (a) on the frame.

C is a driving pulley on the shaft B and D, is a circular flanch attached to the shaft B, said flanch having acollar E upon it, which collar is attached to two slides F F which work upon the upper part of the frame A. To the shaft B there are attached longitudinally at opposite sides or points two flanches G G, which are grooved and have slides (b) (b) fitted in them. The flanches G are connected with the flanch D and the slides (Z9) are connected with the collar F. To the slides (b) screws (c) are attached which are fitted in oblique slots (d) in plates II on the flanches G, and to these plates cutters I I1 are attached. The cutting edges of the cutters of the cutters I passing into the hollow shaft, as shown in Figs. l and 3. By shoving thecollar E back and forth the' cutters I I1 vwill be moved. in and out from the shaft B, that is from its inner edge or side. This will be understood by referring to Fig. 3. To the back ends of the slides F F springs J J are connected by rods (e) (e).

In the drawings only one of the cutters I is shown as being allowed to expand, the other I1 being fixed. This, in some cases, may be preferable, and consequently both or one cutter only may be made to vibrate, as the nature of the work requires.

K K1 represent two feed rollers placed one over the other and transversely on the frame A directly in front of the shaft B (see Figs. 1 and 2). To the end of the roller K1 a pinion L is attached. y

M is a shaft also placed on the upper part of the frame A and parallel with the rollers K K1. This shaft has a driving pulley N on ongl end and a part pinion O on the opposite en P P are two rods, one end of which is attached to the slides F F and the opposite ends are hooked or bent and bear Vupon the shaft M at its end in which pins are placed to act upon the rods P P, as will be presently described.

Q Q are two discharging rollers which are placed on the upper part of the frame A and transversely across the end of the shaft B opposite to the end where the rollers K K1 are placed.

The operation will be readily seen; motion is given the shaft B by a belt which passes around the pulley C on the shaft B and `collar E is moved forward and the cutters I I1 one or both forced inward by the slides (o) (o) and the cutters act` upon the stick R and cut a\handle. When the pins (f) pass the hooked ends of the rod P the collar E and cutters I I1 are brought back to their original position by the springs J J and the teeth of the part pinion O again come in gear with the pinion L and the stick R is again fed a certain distance into the shaft B to be acted upon by the cutters; the handles being cut side by side upon the stick and not quite separated, so that the stick of handles ters I i, one or more attached or tted to the hollow shaft B When the above parts are arranged and operated as herein shown and described for the purpose specied.
